Coal Gas | Coal Mine Methane | Coal Seam Methane

Coal mine methane (CMM) is a type of gas present in active, working mine sites. This gas is extracted from the air in the coal mine helping improve safety and preventing uncontrolled release of methane to atmosphere. CMM is a mixture of methane & air released during the process of coal mining and must be vented for safety reasons.
